The aim of this study was to determine correlations between the multi-dimensions of life satisfaction (self-esteem, friend, school, environment, family, self) and self-esteem by considering loneliness as a dependent variable. The sample consisted of 448 secondary school students; 208 (46.4%) of them were male and 240 (53.6%) of them were female students. For this purpose, Obesity Determinant Measure, Multidimensional Student Life Satisfaction Scale and Rosenberg Self-Esteem Scale were used. It was concluded that the Multidimensional Student Life Satisfaction Scale predicted loneliness negatively. Obesity, being sometimes a handicap for life satisfaction, also predicted loneliness negatively for this population. A negative correlation between self-esteem and loneliness was estimated; regarding the sub-dimensions, negative correlations were found between friend, school, environment, family, self, and loneliness.
Key words: adolescents; life satisfaction; obesity; subjective well-being.
